For MATLAB, there exist many high quality free and/r open source toolboxes from community and academia.

Also there are high quality free and/or open source alternatives.

GNU Octave https://octave.org and Octave online https://octave-online.net/

Freemat https://freemat.sourceforge.net/ (sadly no ongoing development)

Scilab https://www.scilab.org/ and Scilab online https://cloud.scilab.in/

Jack has good advice for embedded software developers which is also useful in other contexts like product development and general software development (desktop and web app) in this last news letter.
